大弓

Thus, this is the advantage of the crossbow versus the bow.

这恰恰是弩对弓的优势之一，拉弓要用很大的力气，时间越长，越难控制瞄准的稳定。

He laid the notch of the arrow on the oxhide bowstring, and drew both notch and string to his breast till the arrow-head was near the bow; then when the bow was arched into a half-circle he let fly, and the bow twanged, and the string sang as the arrow flew gladly on over the heads of the throng.

他运气开弓，紧捏着箭的糟口和牛筋做就的弓弦，弦线紧贴着胸口，铁的箭镞碰到了弓杆。他把兵器拉成了一个拱环，借大的弯弓鸣叫呻喊，弦线高歌作响，羽箭顶着锋快的头镞飞射出去，挟着暴怒，呼啸着扑向前面的人群。

This method offer the real bases and theoretical foundation to detection of the dynamic envelop line of the pantograph.

受电弓动态包络线是指受电弓外形轮廓在垂直方向的上下最大振动量和水平方向的左右最大摆动量所形

In rats treated neonatally with monosodium glutamate the leu-enkephalin and norepinephrine contents in the brain and spinal cord did not change obviously, but the dopamine content of the telencephalon increased significantly, as compared with the control.

本工作分别采用新生期大鼠注射谷氨酸-钠损毁弓状核区及电刺激弓状核区的方法，观察对脑和脊髓内亮-脑啡肽、多巴胺和去甲肾上腺素含量的影响。

Rats in experimental group were placed on the expansion appliance, inserting into the diastema between the first and second molars, then stick to molar lingual using light-cured resin for retention.

实验组采用0.014澳丝弯制双眼圈簧样扩弓装置，插入第一、二磨牙牙间隙，用光固化树脂粘结在大鼠磨牙舌侧进行固位；对照组安装未加力的同型扩弓装置。

MethodsSodium Hyaluronate was injected into the palatoglossal arch, palatopharyngeal arch and root of the tongue of eight Wistar rats. An electroencephalogram, electromyogram and oronasal airflow were recorded by PSG before and 4 weeks after injection when rats were under light anesthesia, which was expected to be similar to the sleep state.

方法将8只Wistar大鼠的双侧舌腭弓、咽腭弓及舌根处注射透明质酸钠，分别于注射前及注射后4周，以浅状态模拟睡眠状态，用多导睡眠仪监测动物的脑电、肌电及口鼻气流。

It means that in the lower part pedicular screws must be introduced at a more convergent angle than in the upper part if we do not want to break any cortical of the vertebral body.

这意味着，假如我们不想打坏椎体的骨皮质，在椎弓根的下半部打入椎弓根螺钉时的汇聚角必须比上半部大。

Small holes could be bored with bradawls, but larger ones required drilling with a bow drill, the bow rotating the metal bit through the wood.

小孔可能会厌倦了bradawls，但需要较大的钻头钻井一弓，弓旋转穿过树林的金属位。

How to ensure sufficient mechanical strength and stiffness but small equivalent quality to improve the dynamic behavior of the pantograph catenary system is a serious problem of the pantograph design.

在满足强度与刚度的前提下，最大限度减小受电弓归算质量，以改善弓－网动态性能是受电弓设计的关键问题。

The length of mandibular dental arch is controlled under weak genetic factors. Both maxillary and mandibular crowding are influenced by the environmental factors.

上下颌牙量大小和上颌牙弓弧长受较强遗传控制，下颌牙弓弧长受弱遗传控制，恒牙列拥挤度遗传度很低，受环境因素影响较大。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
